【正文】 naling work is called the signalling work, No. 7 signaling work system is the signalling work system. No. 7 signaling work system is the core of the modern munication work, it supports the current all the business of the whole munication work, the telemunication work data work to the cellular telephone work the whole munication industry are dependent on the No. 7 signaling work system. No. 7 signaling work system itself is a data work, and provides a set of protocols and message types of standard, so all signaling and control information can be in the form of data message transmission and can support the infinite variety of data. No. 7 signalling work is one of the three supporting work of telemunication work, is an important part of telemunication work, its application is very extensive. So far our country has been established by senior signalling (HSTP), lowlevel signalling (LSTP) and a large number of signaling point (SP), consisting of tertiary really makes as neural work and supporting work of telemunication work. Therefore no. 7 signalling work operation quality directly affects the telemunication work and its various work operation stability and actual benefits. With the increasingly development of munication work, the transmission quality enhances unceasingly, digital munication has been widely used. Due to No. 7 signalling system has many wellknown advantages, No. 7 signalling gradually replaced with road signaling applications in the field of all kinds of munication, in our country has initially formed the independent No. 7 signalling work. Key words: signaling channel mobile munications work base station 1: the signal is divided into with road and road signaling two, ss7 is mon way signaling, said speech signal from a signaling message transmission, is at present our country mainly adopts technology. It has a large capacity of transmission, faster speed, the advantage of high channel utilization, to meet the demand of modern digital munication applications. First of all, introduced the munication work can be divided into work and work, and in the work and the munication work foundation. Run by the signaling protocol in the work can be mainly divided into: China39。另一輔助控制模塊 SACEN7 完成Level3 (第三級 )的鏈路路由轉(zhuǎn)換功能。 信令網(wǎng)集中檢測系統(tǒng) 集中監(jiān)測系統(tǒng)采用分層的體系機(jī)構(gòu),主要分為三層:數(shù)據(jù)采集和本地?cái)?shù)據(jù)預(yù)處理層;數(shù)據(jù)處理和存儲層,包括遠(yuǎn)端站、服務(wù)器中心站服務(wù)器和數(shù)據(jù)庫服務(wù)器;數(shù)據(jù)應(yīng)用層。在 信令系統(tǒng)中,信號信息可以是與一群電路有關(guān)的信號信息或是用于網(wǎng)絡(luò)管理的其他信息 ,因此, 信令系統(tǒng)實(shí)質(zhì)上是電信網(wǎng)中各個(gè)處理機(jī)之間用作傳遞信息的專用數(shù)據(jù)通信系統(tǒng),而 信令網(wǎng)作為通信網(wǎng)的支撐網(wǎng)也可視為一個(gè)相對獨(dú)立的數(shù)據(jù)通信網(wǎng)。 MTP2 層保證了兩個(gè)直接連接的信令點(diǎn)之間傳送信令消息的可靠性,但它對信令消息不作任何處理(從用戶層面上看,其實(shí) MTP2 層會向消息碼流中插入定位定界符和差錯(cuò)校驗(yàn)位), MTP3 則是處理信令消息的最低一層。在我們移動(dòng)通信網(wǎng)絡(luò)中,都采用數(shù)字信令數(shù)據(jù)鏈路。下面就著重介紹一下這三要素: 1) .信令點(diǎn)( SP):即為信令網(wǎng)中發(fā)送或接收信令 消息的實(shí)體。在信令網(wǎng)中所運(yùn)行的信令協(xié)議主要可分為:中國一號信令(隨路信令)和 信令(共路信令)。中文 6960 字 畢業(yè)設(shè)計(jì)(論文)外文翻譯 外 文 題 目 NO. 7 signalling system research 譯 文 題 目 信令系統(tǒng)研究 系 部 信息系 專 業(yè) 班 級 電 信 61002 信令系統(tǒng)研究 摘要 信令網(wǎng)是現(xiàn)代通信網(wǎng)的重要組成部分,它支持目前整個(gè)通信網(wǎng)的所有業(yè)務(wù)。首先介紹下,通信網(wǎng)分為信令網(wǎng)和話路網(wǎng),而信令網(wǎng)又是通信網(wǎng)絡(luò)中的基礎(chǔ)。而 信令 是由信令點(diǎn)、信令轉(zhuǎn)接點(diǎn)和信令鏈路組成的。在數(shù)字信令數(shù)據(jù)鏈路中規(guī)定采用 64Kb/s 的速率( PCM 群的一個(gè)時(shí)隙的傳輸速率);在模擬信令數(shù)據(jù)鏈路中,如采用頻分復(fù)用傳輸系統(tǒng)的信令數(shù)據(jù)鏈路,規(guī)定采用 。 3) . MTP3 網(wǎng)絡(luò)層:該層和 SCCP 層一同對應(yīng)于 OSI 的網(wǎng)絡(luò)層。 信令系統(tǒng)的定義 信令是一種局間的數(shù)字共路信令。系統(tǒng)主要完成:實(shí)時(shí)告警監(jiān)控功能 (鏈路、鏈路組、路 由交換機(jī)、處理機(jī)及傳輸告警鏈路利用率鏈路負(fù)荷統(tǒng)計(jì)鏈路、鏈路組、路由組服務(wù)狀態(tài)統(tǒng)計(jì) ) ;集中操作維護(hù)功能;網(wǎng)絡(luò)配置管理 (短路局名及網(wǎng)絡(luò)配置 );故障查詢與統(tǒng)計(jì)功能 (鏈路短路組路由組及設(shè)備本身告警 )。 CCSM 模塊完成交換機(jī) 信令系統(tǒng)的第二級信號鏈路功能 (實(shí)現(xiàn)信號的差錯(cuò)檢測、差錯(cuò)校正等 )和第三級消息處理、信號網(wǎng)管理功能,此模塊采用標(biāo)準(zhǔn)接口經(jīng)數(shù)字交換網(wǎng)絡(luò) (DSN)和數(shù)字中繼模塊所形成的信號鏈路與另一數(shù)字程控交換機(jī) (或信號 STP)相連接。并且無論是在信令協(xié)議制定方面還是信令網(wǎng)的建設(shè)維護(hù)和管理應(yīng)用方面,我國都處于很落后的狀況,因此緊跟世界前言發(fā)展并完善 信令是現(xiàn)在必然的趨勢。ll introduce NO. 7 basic concepts of the . NO. 7 signalling work is the basis of munication work in China, it is responsible for signaling interaction to plete a business requirements of users. The NO. 7 signaling is posed of signaling point, signalling and signaling links. Here are emphatically introduce the three elements: 1) signaling point (SP) : is the signaling messages are sent or received in the signalling work entities. If the signaling messages are sent, you can call the signaling point source signaling point。 And double flat structure is mainly in order to improve the reliability of signalling work, we usually use A and B double flat structure, namely the HSTP usually e in pairs, and the two are linked together, so even if A HSTP fault, another can replace: NO. 7 signaling load mode, there are three, respectively is: the TDM, ATM and IP。 For No. 7 signalling work performance data for statistics and can read the work status data and determine the performance of work, such as business data collection, the determination of traffic and load, business reports。 ATM at a rate of 2 m, the use of E1 line of 30 time slot (0 time slot is used for the clock, 16 slot is used to transfer management message)。 Lower bit error rate of channel transmission。由于信令網(wǎng)是一個(gè)速度快 ,可靠性好的分組交換網(wǎng) ,網(wǎng)絡(luò)管理中心的操作員可以對通訊網(wǎng)進(jìn)行遠(yuǎn)程的實(shí)時(shí)的測試、診斷、監(jiān)視、控制和管理 ,并且不干擾正常的數(shù)據(jù)通訊。實(shí)現(xiàn)對 信令網(wǎng)的動(dòng)態(tài)和微觀分析管理,從而實(shí)現(xiàn)對一個(gè)地區(qū) 信令網(wǎng)及信令網(wǎng)上承載業(yè)務(wù)的話務(wù)、質(zhì)量、經(jīng)營、服務(wù)等指標(biāo)的分析管理。 NSC 是具有運(yùn)行管理和維護(hù)功能的集中維護(hù)中心 (0Aamp。 以上就是有關(guān)七號信令的一些基礎(chǔ)知識,移動(dòng)通信技術(shù)不僅要正確的應(yīng)用這些技術(shù),而且還有后期的維護(hù)管理等等,七號信令也能夠提供這方面的幫助,主要是根據(jù)系統(tǒng)報(bào)告,人機(jī)命令和 MPTMON 指令顯示所查詢的的 信令系統(tǒng)狀態(tài),迅速確定故障的位置,然后予以排除,至于維護(hù)的內(nèi)容在此不多說。 MTP2 層在 CPCI 平臺的 CPC 扣板處理,在 32 模平臺上是LAP 板處理。 信令的層次結(jié)構(gòu)圖如下: 我們 HLR 系統(tǒng)主要運(yùn)用 信令的 MAP 協(xié)議層,其具體包含: SCCP、 MTP MTP MTP1。 3. 信令的基本概念: ( Link):即指用來傳送信令的物理信道,一般為 E1 線的一個(gè)時(shí)隙; ( LinkSet):具有相同屬性鏈路的集合,也可以說成是到一個(gè)局向的所有鏈路組成的集合。 隨著通信網(wǎng)的日益發(fā)展,傳輸質(zhì)量的不斷提高,數(shù)字通信已廣泛使用。 引言 通用性很強(qiáng)的 (Signaling System )是國際電報(bào)電話咨詢委員會 (CCITT)于 1980 年提出來的 ,現(xiàn)在 信令通過多次擴(kuò)展修改 ,已形成了一個(gè)完整的信令體系。 信令我們也可以說成是為了完成某種業(yè)務(wù)的操作交互而發(fā)出的一些指令或命令。直連方式即指兩個(gè)信令點(diǎn)直接相 連,中間不經(jīng)過任何轉(zhuǎn)接;而準(zhǔn)直連方式是指兩個(gè)信令點(diǎn)間的連接是經(jīng)過一個(gè)或多個(gè)信令轉(zhuǎn)接點(diǎn)轉(zhuǎn)接的。 2) . MTP2 信令鏈路層:對應(yīng)于 OSI 模型中的數(shù)據(jù)鏈路層。信令消息 處理內(nèi)部又可以分為三大塊:消息識別、消息分配和消息編路。 信令系統(tǒng)的優(yōu)點(diǎn) 信令系統(tǒng)最適合由數(shù)字程控交換機(jī)和數(shù)字傳輸設(shè)備所組成的綜合數(shù)字網(wǎng),能滿足現(xiàn)在及將來傳送呼叫控制、遙控、維護(hù)管理信令及處理機(jī)之間事務(wù)處理信息的要求,提供了可靠的方法,使信令按正確的順序傳送又不至丟失或重復(fù)。遠(yuǎn)端站和中心站要使用廣域網(wǎng)絡(luò)系統(tǒng)來連接,廣域網(wǎng)可采用。 S1240和 EWSD交換機(jī)中與 20多條,可用來顯示、
